I have been using Pantothenic acid, 500 mg capsules for adrenal support, coping with stress, for 30 years. I take 1 or 2 capsules at a time, morning, midday, before bed, with exercise. Take as much as you need to feel good. There is no problem with headache, stomach irritation, overdose, toxicity, buildup or addiction. It is water soluble. It cannot be stored in the body. Any excess is excreted. We all have stress. My experience is that this nutrient supports the adrenal gland and helps me cope with the stress in my life. I can feel better in ½ hour or less. Always use B-5 Pantothenic acid with Ester C, 500 or 1,000 mg tablets, because these 2 nutrients are synergistic and work together to support the adrenal gland. Adrenal exhaustion is very common and not recognized by doctors. Most B-complex formulas contain only 100 mg pantothenic acid. Even if you take 3 capsules of b-complex daily, you will only get 300 mg Pantothenic acid all day. I use and recommend much more than that. You will feel the benefit.
Pantothenic acid is also a necessary co-factor to metabolize the nutrient phosphatidyl-choline, a part of the B-complex, into the brain neurotransmitter acetyl-choline, which is responsible for memory.
I bought 500 mg Pantothenic acid capsules from 5 different companies and weighed them. NOW capsules had the least amount of filler and therefore the smallest capsules. This is important for someone, like me or you, who consumes many capsules per day.

I have been using this 500 mg tablet of vitamin B-6 for years.
The tablet is smaller than a 500 mg capsule.
I appreciate that it is time release.
B-6 gives support and soothes the nervous system.
I am naturally sensitive to light, sound and various noises.
With enough B-6, I don&#39;t care if a 747 lands in my living room.
B-6 is a necessary co-factor (with vitamin C)
to convert the raw material precursor 5HTP (tryptophan) to the neurotransmitter Serotonin.
Serotonin is the brain neurotransmitter that is enhanced by Prozac/Paxil/Zoloft and other SSRI&#39;s.
It is possible that some depression and other problems are nothing more than a B-6 deficiency.
B-6 is also necessary for the synthesis of 3 other important brain neurotransmitters.
Although this supplement gives 25,000% of the Daily Value,
many people need and benefit from this level of supplementation.
Also, I have Pyroluria, a genetic condition which causes destruction and excretion of B-6.
It is a condition which is often not diagnosed by doctors,
although there is a urine test available on the internet for $55.
I use 2 or 3 tablets daily to feel good.
Without this supplementation, I experience some of the symptoms of B-6 deficiency,
such as anemia and fatigue and sensitivities to light and sound.
Too much can cause temporary numbness in the toes, which goes away if you decrease the doseage.
This is an important part of the B-complex.
However, the amount of B-6 in most B-complex supplements is only 100 mg.
This is not enough to really get the full benefit of B-6.
This is why a 500 mg tablet is very useful.
Also my wife found it valuble to treat morning sickness during pregnancy.

This is a seriously powerful product. NAC is used for bronchitis, sinusitis, otitis media (middle ear infection), pneumonia and lung problems, and to protect the liver against Tylenol/acetaminophen poisoning and alcohol. The time release aspect of this product is important. Only use an NAC product which is time released because otherwise it metabolizes through the liver and out of the body in 1.5 hours. This product is well tolerated, does not cause headache or stomach upset. For acute problems, viruses, colds, flu or congestion, use 3 or 4 tablets, every 4 hours. You can feel congestion clearing in under 1 hour. This should also be used by people with HIV and cancer. I have seen this product work well many times. I always keep a spare bottle in my arsenal. If Bird Flu comes, I'm ready.

Phosphatidyl Serine is a great supplement for memory enhancement, but this product has an unnecessary amount of filler in it and the capsule is larger than it needs to be. Jarrow PS100 (120 caps) has the same amount of nutrient in it, with a smaller capsule. Both are equally effective.

Nice small tablets. This is important for people who consume mass quantities of supplements! Note to other companies: Please leave out all the extra filler, which makes big tables and capsules!
Also, this product seems to cause NO headaches or stomach upset.
Reasonably priced.

This tablet weighs 1,520 mgs!
Full of filler!
Source Natural is a good, clean honest company. They produce many good products that are small tablets, made without too much extra filler. However, this product is a big mistake. To produce a 500 mg B-5 tablet which weighs 1,520 mg. only shows that somebody is just not thinking. The tablet is a large, oblong, horse pill. One alone is bad enough. However, a serious vitamin guy like me may consume -3- 500 mg B-5 supplements, 4 times daily, for a total of 12 tablets or capsules per day. This is just one component in a powerful program, so size matters. That’s a large quantity of filler that I just don’t need or want. Thanks, but no thanks. NOW Pantothenic acid 500 mg capsule is the smallest, weighing in at 642 mgs.

The product is good, but the capsule is large enough for a 250 mg size. Obviously, there is too much filler packed in there.
They should put this in a much smaller capsule, which would be appropriate for a 30 mg zinc capsule, and more convenient to swallow, especially for people who swallow many capsules.

This product is effective for this specific purpose - Lower Back Support / Pain / Injuries. I cannot understand why they say to use 1 tablet per day. That is too low. I find that it is quite effective, quite fast, if I use 2 to 4 tablets at one time for an acute problem. Also, 1 tablet two or three times a day for longer term. Experiment with more than 1 tablet per day for better results.
Great product from excellent company.
Many people with lower back problems could benefit from this product.

I thought I would try this out on my wife. Worked great. I gave it to a co-worker. She loved it. Cleared a persistent cough from her lungs. She gave it to her mother. worked great. Cleared her lungs. Now I keep a bottle here for the next time my wife needs it. This product is powerful and effective.
